stp transmit-limit

Syntax

stp transmit-limit limit

undo stp transmit-limit

View

Ethernet interface view, port group view, Layer 2 aggregate interface view

Default level

2: System level

Parameters

limit: Sets the maximum number of BPDUs the ports can send within each hello time, in the range of 1 to 255.

Description

Use stp transmit-limit to set the maximum number of BPDUs that the ports can send within each hello time.

Use undo stp transmit-limit to restore the default.

By default, the maximum transmission rate of all ports is 10. Each port can send up to 10 BPDUs within each hello time.

Configured in Ethernet interface view, the setting takes effect only on the interface.

Configured in port group view, the setting takes effect on all member ports in the port group.

Configured in Layer 2 aggregate interface view, the setting takes effect only on the aggregate interface.

Configured on a member port in an aggregation group, the setting takes effect only after the port leaves the aggregation group.

A larger maximum transmission rate value requires more system resources. An appropriate maximum transmission rate setting can prevent spanning tree protocols from using excessive bandwidth resources during network topology changes. Hewlett Packard Enterprise recommends that you use the default value.

Examples

# Set the maximum transmission rate of port Ethernet 1/0/1 to 5.
